Application led August 12, 1907. Serial No. 388,258.

To al? whom it may concern.

Be it known that I, MONTGOMERY L. GAN- BER, a citizen of the UnitedStates, residing at Norristown, in the county of Montgomery and State ofPennsylvania, have invented certain new and useful Improvements inAutomatic Electric Gas-Range Lighters; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in electrical gas lighters.

The object of the invention is to provide'a device of this characteradapted particularly for use in lighting gas ranges, and having anautomatically operating switch or circuit closer arranged therein,whereby when the device is held in an operative position, the circuitwill be automatically closed to cause a spark, and when the device ishung up in an inoperative position, the circuit will be automatically broken.

V\ ith this object in view, the invention consists of certain novelfeatures of construction, combination and arrangement of parts as willbe more fully described and particularly pointed out in the appendedclaim.

In the accompanying drawings, Figure 1 is a perspective view of thedevice, showing the preferred arrangement of the same when not in use; Fig. 2 is a vertical longitudinal sectional view of the lighter when inposition for use; Fig. 3 is a similar view showing the circuit closingmechanism in ino erative position; and Fig. 4 is an enlarge detailedsectional view of the circmit closing mechanism removed from the handle.

Referring more articularly to the drawings, 1 denotes the ighter, whichconsists of a handle, 2, preferably formed of a suitable non-conductingmaterial. On one end of the handle is arranged a metallic ferrule, 2a,having a sleeve 2b, which is interiorly screw threaded to which issecured a screw threaded metallic tube, 3, which may be of any desiredlength, and is preferably curved as shown. On the outer end of the tube,3, is arranged a threaded socket, 4, into which is adapted to be screweda conducting plug, 5, on vwhich is arranged a hollow perforated tip, 6,in which are arranged the terminal circuit wires, which are connected bya coiled sparking wire, 7, inthe usual manner.

Arranged in the hollow handle, 2, is an 4automatic circuit closingdevice, consisting of a short tube, 8, which is preferably formed vofglass, but which may be vconstructed of any suitable non-conductingmaterial. In oneof the closed ends of the tube is adapted to be insertedthe end of one of the circuit wires, 9, the other circuit Wire 10extending forwardly through the tube 3 and connecting with a contactpoint, 12, arranged in a plug, 13, which is disposed in the end of thetube, 3, and suitably insulated therefrom adjacent to the end of thethreaded socket, 4. Also inserted in the closed end of the tube 8 is ashort conducting wire, 14, said end of the wire 14 is secured betweenthe handle and its ferrule and being insulated from the end of the wire9 by means of the plug which closes the lend of the tube, said plugbeing formed of a suitable insulating material.

The outer end of the short conducting wire 14 is electrically connectedto the tube, 3, which is adapted to form a conductor through which thecurrent is carried to the plug 5 in the socket 4, and from said plug thecurrent is transferred to one of the terminal wires in the tip, 6. Theelectrical current is transferred to the other terminal Wire in the tipthrough a contact point, 15, on the end of said terminal wire, saidpoint being adapted to engage the contact point, 12, in the plug, 13,which is arranged in the end of the tube, 3.

In the tube 8 is placed a small quantity of mercury, which, whenpermitted to drop to the forward end of the tube, will surround the endof the circuit wire, 9, and the short conducting wire, 14, whose outerend connects with the metal portion of the tube, 3, thereby completingor closing the circuit between said ends of the wires and permitting thecurrent of electricity from the batteries to pass through the coiledsparking wire connecting the ends of the short terminal wires in the tipand causing a spark to form on said coil. r1`he arrangement ol' the tube8 in the handle 2 is such that when the handle and tip are helddownwardly, the mercury will move forwardly in the tube, 8, and thuscomplete the circuit as hereinbefore described. When the handle and thetip are again elevated, the mercury will roll back to the opposite endof the tube, thereby breaking the circuit and preventing the sparking ofthe coil.

The ends of the conductor wires 9 and 10 are Iconnected to a suitableelectrical supply, the same being -shown in the present instancesupported when not in use, the lighter being hung upon the casing, 16,with the tip end projecting upwardly, thus causing the mercury in thetube 8 to break the circuit.

. Whenxit is desired to use the lighter, it is simply necessary to takethe same down from its` support on the casing, 16, and turn the tipthereof downwardly, which operation automatically completes the circuitand causes a s ark to form in the tip in the mannerherein eforedescribed.

An electrical gas lighter constructed as shown and described herein,will be simple, strong and durable in construction, practical, reliab eand automatic in operation, and well ada ted tothe purpose for which itis inten ed. v

`Havin thus fully described my invention, what I c aim as new and desireto secure-by Letters-Patent, is: c

An automatic gas range lighter comprising a hollow handle, with a errulethereon, having an internally screw threaded sleeve therewith, 'a tubedetachably connected to said sleeve, a mercurial tube in said handle,

having a. plug therein for closing the same,

circuit wires, one of which is connected to i one end thereof connectedto the plug of the mercurial tube, its other end being secured betweenthe handle and ferrule, a p` ug in the outer end of the detachable tubehaving a contact oint therein, lthe circuit wire in the detachable tubebeing inserted in the plug of the detachable tube and contacting withsaid point, a perforated socket connected to the outer end of thedetachable tube and having a plug therein which is spaced from the plugof the detachable tube, saidplug of the socket having a contact pointwhich engages the contact point in the plug of the detachable tube, andsaid plug ot the socket having terminal contact wires therein which areconnected together by a coiled sparking wire, substantially asspecified.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. MONTGOMERY L. GANSER.
